ESP12_DEV

A development board for the ESP12 and ESP12E WiFi modules. Featuring some useful sensors and required peripherals to make it work.

Rev 00

ESP12_DEV_00

Initial board version with 3.3V LDO and 5V LDO.

Known issues :

  • TXB0106 symbol is wrong resulting in a short circuit
  • 3V3 LDO will get hot when board is powered with 12V

Rev 01

ESP12_DEV_01

  • Replaced the 3.3V LDO with a TPS562209 based switching power supply to reduce power dissipation.
  • Added more capacitors to increase stability

Features

  • 3V3 level FTDI-compatible UART pin header
  • push buttons for reset and boot
  • 7 - 12VDC power input
  • 5V power input possible when bypassing internal 5V LDO with 0 Ohm resistor or ferrite bead.
  • 6 bidirectional 5V I/O pins
  • Microphone
  • Temperature and humidity sensor
